what is the relationship between exposing to a virus and developing immunity to it? cite evidence from the text to support your response
Answer:
Exposure to a virus is closely related to the development of immunity, since the immune system is responsible for creating antibodies in response to the presence of potentially harmful biological agents, such as these viruses.
Explanation:
Viruses are biological agents that can produce diseases when they enter the body of a living being. In response to contact with a virus, the immune system synthesizes specific antibodies to combat the foreign biological agent.
Antibody immunity can be of two types. It is fast when it is mediated by immunoglobulins M (IgM), which attack the virus anywhere, while the late and prolonged response is due to the development of immunoglobulins G (IgG).
An example of immunity to a virus occurs with the exhibition to the virus of the Dengue, that creates permanent immunity to the viral serotype to which an individual is exposed.
The acquired immunity, mediated by antibodies, is the base for the development of vaccines.

Which statement about plant and animal cells is true?
O Both have a cell wall to give them support.
O Both have a large vacuole to store water.
O Both use mitochondria to release energy.
O Both use chloroplasts to store energy.
C. Both use mitochondria to release energy.
Explanation:
Eukaryotic cells have membrane-bound organelles. These organelles are cellular structures, like the mitochondria, nucleus, lysosomes, endoplasmic reticulum, etc. Eukaryotic cells are both plant and animal cells.
Both have a cell wall to give them support. False. While both plant and animal cells have a cell membrane, only plant cells have a cell wall. The cell wall in plant cells will go around the cell membrane, this protects the cell and gives the cell its shape.
Both have a large vacuole to store water. False. Only plant cells have a large vacuole that stores water. Both plant and animal cells have vacuoles, but the vacuole in the animal cell is much smaller than the one in the plant cell.
Both use mitochondria to release energy. True. As I stated before, both plant and animal cells are eukaryotic, which means they contain membrane-bound organelles. Both of them use the mitochondria to release energy.
Both use chloroplasts to store energy. False. Only plant cells have chloroplasts, animal cells do not. These help capture the energy and nutrients from the Sun, helping the plant be energized and grow.
Answer:
C. Both use mitochondria to release energy.

38
Answer:
2
Explanation:
This question is describing the process of cellular respiration, which is the breakdown of glucose molecule in the cell to yield energy (ATP). However, the process of cellular respiration is further divided into stages viz: glycolysis, Krebs cycle, and oxidative phosphorylation.
Glycolysis is the first stage of the process, which occurs in the CYTOPLASM of the cell. Hence, this question is specifically describing the process of glycolysis. During glycolysis, glucose molecule is broken down in a series of steps to yield a net of 2 ATP molecules.

Answer:
Ecosystem services are the goods and services that biodiversity provides. They include soil formation, the provision of food and fibre, air quality and climate regulation, the regulation of water supply and quality and the cultural and aesthetic value of certain plants and species.
In a solution, solute substances naturally tend to move from areas of higher concentration to areas of lower
concentration.
What is the name of this process?
diffusion

osmosis
Answer:
The process is diffusion
Explanation:
Molecules or substances in solution move by various means. In osmosis, and passive diffusion, water or other substances move across a barrier or membrane.
In diffusion, molecules of a substance, like the solute (dissolved in a solvent) move from regions of high concentration down their concentration gradient, to a region of low concentration.

Edwin wrote the following notes about static electricity. When an uncharged object is placed close to a charged object, the objects can attract or repel each other. When two electrically charged objects are placed next to one another, the objects can also attract or repel. What statement will correct the error in Edwin's notes?
A) An electrically charged object needs to touch an uncharged object before they attract or repel.
B) When an electrically charged object comes close to an uncharged object, it will attract it.
C) If an electrically charged object is near an uncharged object, it will repel it.
D) When two electrically charged objects are placed close together, they only attract.
Answer:
it's An uncharged object.
if its not charged the electrically wont go on it
Explanation:
The statement that will correct the error in Edwin's notes is as follows:
An electrically charged object needs to touch an uncharged object before they attract or repel.Thus, the correct option is A.
How do electrically charged objects produce attraction?The electrically charged objects produce attraction of oppositely charged objects. For example, if a positively charged object and a negatively charged object bring close to each other, they interact with one another. Their forces act in the same direction. i.e. from the positive to the negative charge.
There is an interaction between two oppositely charged objects required in order to furnish attraction, while there is an interaction between two identical charged objects required in order to furnish repulsion.
Whether it is attraction or repulsion, it must be required that an electrically charged object needs to touch an uncharged object.
Therefore, the correct option for this question is A.

Antibiotic resistance can evolve in bacteria via the following mechanisms
Select one:
A. Transformation, conjugation, and transduction.
B. Transformation, reformation, and conjugation
1
O C. Reformation, fission, and conjugation.
O D. Transformation, fusion, and conjugation.
Three mechanisms of horizontal gene transfer that can lead to the evolution of antibiotic resistance in bacteria are transformation, conjugation, and transduction. Hence option A is correct.
What is transformation?Transformation is the process by which bacteria take up DNA from their surroundings and incorporate it into their genome.
Conjugation involves the transfer of DNA from one bacterium to another through a pilus, a thin tube-like structure.
Transduction occurs when bacteria acquire DNA from a virus that has infected them.
These mechanisms of horizontal gene transfer are significant because they allow bacteria to quickly adapt to new environments and acquire antibiotic resistance genes that can help them survive in the presence of antibiotics.
This can lead to the development of superbugs that are resistant to multiple antibiotics and can cause serious infections that are difficult to treat. It is important to use antibiotics judiciously and to develop new antibiotics and alternative treatments to combat antibiotic resistance.
Hence option A is correct.

A biologist pollinates a true-breeding yellow flower with pollen from a true-breeding red flower of the same species. All of the F, offspring are yellow. The question can be Is flower color polygenic?
What is True breeding plant?A true breeding is a kind of breeding wherein the parents would produce offspring that would carry the same phenotype. This means that the parents are homozygous for every trait.
An example of true breeding is that of the Aberdeen Angus cattle. The cattle have been black for many generations, which is an indication that such trait passed on from many generations remains pure.
With plants, true breeding occurs when plants produce only offspring of the same variety when they self-pollinate. For instance, a plant that has blue flowers will produce only seeds that will grow into plants that have blue flowers.
Therefore, A biologist pollinates a true-breeding yellow flower with pollen from a true-breeding red flower of the same species. All of the F, offspring are yellow. The question can be Is flower color polygenic?
